Gorilla Gray Foam Multipurpose Insulating Sealant 12 oz

The Gorilla Gray Foam Multipurpose Insulating Sealant (12 oz) is truly a standout product for anyone tackling home repairs, insulation projects, or general sealing tasks. This foam delivers exactly what you expect from the Gorilla brand—strength, reliability, and outstanding performance. The gray color is a huge plus because it blends much better with concrete, stone, metal, and darker building materials compared to the typical bright yellow foams. The expansion is controlled and consistent, making it easy to fill gaps, cracks, and crevices without creating a mess or massive overflow. Once cured, the foam is firm, durable, and weather‑resistant, making it ideal for both indoor and outdoor use. It seals beautifully against drafts, pests, moisture, and noise. The adhesion is excellent on a wide range of surfaces—wood, brick, metal, cement, you name it. The 12 oz can offers great coverage, and the precision applicator makes it simple to get a clean, accurate bead exactly where you need it. Whether you're sealing around pipes, filling wall gaps, insulating windows and doors, or tightening up energy efficiency, this foam gets the job done quickly and effectively.

Item worked exactly as described . Less is definitely more !! I would recommend

Worked as good as I would have hoped. It foams up a lot so you don't need to spray much at all. Filled some gaps around the house for the winter.

Availability at good price

I love being able to get delivered

Be prepared to use it all at once. It's super good but once you start you can't just clean up and put it away. Only use little pressure which can be challenging. Expansion is excellent but as stated prepared to use only once which is wasteful in my opinion since I didn't need the whole can. That makes it not cost effective.

This foam is extremely sticky and doesn't expand as well as some others I've used.

This was messy, difficult to use and fell off the surface I was trying to seal as I was applying it. TOTALLY USELESS!

I never received this product after I ordered it I was informed it was not available. Which was very annoying because I'm going to have to order it somewhere else and I would have picked a different product if I had known this one wasn't going to be available. I have a project I'm trying to do which is now going to be delayed by several days.

First, I LOVE Gorilla products. I always seek them out. That is primarily because they are not made with animal inputs i.e. they are Vegan. SO when it comes to anything adhesive - glue, tape, etc - Gorilla is the only brand I buy. This is my first purchase of Gorilla spray insulation and it, unfortunately, did not perform at the same level as other similar products I have used in the past. Specifically, the foam insulation would not come out of the can, did not create a continual spray of insulation. I had to constantly stop and shake the can. So I can't recommend this particular Gorilla product AND I would absolutely recommend all other Gorilla products!
